SPECIFICATION forming part of Letters Patent No. 600,418, dated March 8, 1898.

Application filed August 30, 1897. $81M 1 (N0 model) To aZZ whom it may concern.-

Be it known that I, WILLIAM D. GRACE, a citizen of the United States of America, residing at Frugality, in the county of Cambria and State of Pennsylvania, have invented certain new and useful Improvements in Miners Lamps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to miners lamps; and it consists of the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

The object of the invention is to apply a pick in connection with the body of a miners lamp for regulating and picking the wick in order to produce a better light and to dispense with the primitive means of accomplishing this result which has heretofore been employed.

In the accompanying drawings, Figure 1 is perspective view of aminers lamp embodying the invention. Fig. 2 is an elevation of the lamp, showing the pick removed therefrom and at one side thereof. Fig. 3 is a section on a line a as, Fig. 1.

Referring to the drawings, wherein similar numerals of reference are employed to indicate corresponding parts in the several views, the numeral 1 designates the body of the lamp, havin a wick-spout 2, a hinged lid or cover 3, and a securing-hook 4, all of any well known and preferred form of construction. Attached to the body 1 and extending vertically thereof is a sheath 5, preferably formed with a lower opening on each side and having a movable front side 6 and an upper outwardly-bent retaining-lip 7. The outer side 6 has a spring action and is narrower at its lower end, as at 8, than at its upper end, where it has a suitable bearing against the adjacent portion of the sheath, the latter in the present instance being preferably constructed from a single piece of material, having side flanges 9, retaining-tongues 10, and rebent upon itself to form the outer movable side 6. This sheath is soldered to the body 1 or otherwise fastened thereto; but the exact mode of construction may be varied so long as the improved fea tures, including the outer movable side and the upper tongue, are preserved or equivalent features substituted therefor. A pick 11 is removably mounted in the sheath and comprises a V- tapered shank 12, with a lower pointed end 13 and an upper flattened head 14, which overhangs or projects over one side of the said shank, and when in position in the sheath, as shown in Fig. 1, the said head projects slightly over the front side 6. When the pick is in the sheath, as shown in Fig. 1, the tongue 7 is adapted to take against the inner portion of the said head let to prevent accidental disengagement of the pick from the sheath, and in withdrawing the pick for use the outer movable side 6 springs out from the body of said sheath, when the separation of the parts can be easily accomplished. The position of the tongue 7 is such that when the pick is Withdrawn from the sheath it will be prevented from striking the rim of the cover 3, which slightly projects over the upper portion of the body in devices of this character of the ordinary form of construction.

The pick set forth is intended for use in picking the cotton up and dressing it to make a clear bright light and to prevent a miner from burning his fingers or hammering his lamp on a piece of wood or other material, that sooner or later dinges it and causes it to leak, necessitating the purchase of a new one,

and by carrying the pick in connection with the lamp it is always in position for use and may be applied to the ordinary form of miners lamp without materially increasing the cost of the same, especially when considered in connection with the additional advantages accruing from the arrangement set forth.

It is obviously apparent that many minor changes in the details of construction and arrangement of the several parts might be made and substituted for those shown and described without in the least departing from the nature or spirit of the invention.

Having thus described the invention, what is claimed as new is- 1. A miners lamp having a sheath on the body thereof with an outer movable side and an upper lip, and a pick with an outwardlyprojecting flattened head, substantially as described.

2. A miners lamp having a sheath upon the body thereof tapering toward the lower end and provided with an outer movable side and an upper lip and a tapering pick removably engaging said sheath, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscrib- IO ing witnesses.

WILLIAM D. GRACE.
